Analysis apparatus

Abstract

Pulse laser light transmitted through a laser light transmission optical fiber to an optical system unit passes through a distribution reflecting mirror and is condensed by a condenser lens group. The condenser lens group irradiates the condensed laser light onto an analysis object. The fluorescence emitted as a result of the irradiation of the pulse laser light onto the analysis object is condensed by the condenser lens group and is reflected by the distribution reflecting mirror. The optical system unit transmits the fluorescence reflected by the distribution reflecting mirror through an fluorescence transmission optical fiber to a fluorescence measuring instrument. The fluorescence measuring instrument determines the quantity of elements included in the analysis object on the basis of the fluorescence.
